If the minimum repayment amount is not paid before the due repayment date, as long as the minimum repayment amount is paid within the next three-day repayment grace period, it is not overdue. In addition to the grace period for repayment, Pufa Credit Card also allows repayment difference. This is because Shanghai Pudong Development Bank provides tolerance service. When the cardholder of Shanghai Pudong Development Credit Card repays in full in the current period, if the unpaid part of the account does not exceed 10 yuan after the due repayment date, Shanghai Pudong Development Bank will regard the cardholder as fully repaid, and this unpaid amount will be automatically transferred to the next bill, which is not overdue.
